Amanda Bynes' parents, Lynn and Rick, will ask a court in Friday if they can be granted temporary conservatorship in order to allow them control over their daughter's financial and personal affairs.

Their decision comes after Bynes was detained Monday night on a 72-hour psychiatric hold after allegedly setting a fire in the driveway of a home near her parents' house in Thousand Oaks, Calif., according to reports from E! News.

Police were reportedly called to an elderly woman's home in Thousand Oaks, Calif. Monday night when an unidentified person noticed the driveway was alight, according to TMZ.com.

Upon police arrival Bynes, who allegedly burned parts of her clothing, was reportedly questioned about the incident and subsequently placed on a 5150 hold due to her responses. She was then transported to a psychiatric hospital for evaluation and legally she can be held for up to 72 hours.

The unidentified resident whose driveway was on fire reportedly did not learn about the incident until after police arrived. The authorities asked her questions in an attempt to understand Bynes' motives.

"[Police asked] 'do you know anyone by the name of Amanda Bynes, or why she would have some vendetta against you?'" the elderly woman told TMZ.com, adding that she replied "no."

The parents of Bynes, Lynn and Rick, are reportedly concerned for their daughter's mental well being but feeling helpless because she is an adult.

"It doesn't take a rocket scientist to look at Amanda and surmise that she is having some sort of crisis. Her makeover is just one example of her troubling behavior. Her parents just wish the media would leave Amanda alone, because it's only making the situation worse. Amanda is lost and she refuses to get help," a source reportedly told RadarOnline.com.

"Her parents are powerless to do anything because she is 27 years of age and there is very little they can do, under the law," the source added.
